Chang Yu
I've noticed that the story underplays Zhang Ye's talents. Even if he's got a full script and video in his head, it requires major improv skills to adapt everything (sometimes even on the fly). Those skills come from him, not the ring... and while they wouldn't be enough to overcome the odds of him being a superstar, it means he's not exactly your average entry-level talent, even without the ring. But it's easy to read the story and assume it's all him cheating with the ring, when in fact the ring would barely be useful to a true cheater.
